How can I check if CONFIG_SND_DYNAMIC_MINORS is enabled,

Look into the .config file in your kernel source tree.

I've been having a lot of trouble assigning 10 USB soundcards, and it's been doing fishy things when I change who's plugged in to which usb hub.

It's not easy to distinguish devices that do not have a serial number.

ALSA recognizes all the cards,

This implies CONFIG_SND_DYNAMIC_MINORS is enabled.

but some of the hw:x,y plays through the default hw:0,0.

You mean, to the wrong device?

How did you test this?

Check that the minor numbers in /proc/asound/devices match the actual minor numbers in /dev/snd/.
